Refractive Lens Exchange (RLE) -โ ๐ช๐ต๐ฎ๐ ๐ฌ๐ผ๐ ๐ก๐ฒ๐ฒ๐ฑ ๐๐ผ ๐๐ป๐ผ๐
Refractive lens exchange (RLE) is an operation that replaces your eyeโs natural lens with an artificial lens implant. It aims to reduce your dependence on glasses or contact lenses. The procedure is similar to cataract surgery, but it is performed mainly to correct your vision before a significant cataract develops.

RLE may be suitable if you are over 50, increasingly dependent on reading glasses, or have a prescription that is unsuitable for laser correction. Suitability depends on your eye health, prescription, and daily visual needs.
Younger people with a clear, flexible natural lens are usually better suited to other options, such as laser correction or an implantable contact lens (ICL). Unlike RLE, ICL surgery keeps your natural lens in place.

The surgeon removes your natural lens through a small opening and inserts a clear artificial lens. The procedure usually takes around 20 minutes per eye.
It is normally performed as day-care surgery under local anaesthesia, often using numbing eye drops. You may notice light or pressure, but should not feel pain. You can usually return home the same day.

Your reading habits, computer use, and night driving should guide the choice. Retinal disease, glaucoma, or other eye conditions may limit which lenses are suitable.

Possible complications include infection, increased eye pressure, swelling in the retina, and retinal detachment. Some complications can permanently affect vision.

A careful retinal examination and discussion of your individual risk are essential before deciding on surgery. Removing the natural lens also permanently removes its remaining ability to change focus.

Vision may initially be blurred, and mild grittiness or light sensitivity can occur. These symptoms generally improve as the eye heals. Use your prescribed drops, attend follow-up appointments, and follow your surgeonโs advice about driving, exercise, and swimming.
Halos around lights may become less noticeable with time, although they can persist, particularly with multifocal lenses.
The thin membrane behind the implant can become cloudy months or years later. This is called posterior capsule opacification (PCO), rather than a new cataract, and can usually be treated with a short laser procedure.

No.
RLE is an elective procedure. Continuing with glasses or suitable contact lenses remains an option.
